What is Hours to Decimal?

Hours to Decimal is a conversion method that changes time measured in hours and minutes into a decimal number. This is often used in timekeeping and payroll calculations where it’s easier to work with decimal numbers rather than minutes. For example, 1 hour and 30 minutes would be converted to 1.5 hours in decimal form.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ D = 2 + \left( \frac{45}{60} \right) + \left( \frac{30}{3600} \right) = 2.7583 \]

The Decimal Equivalent is 2.7583 hours.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ D = 1 + \left( \frac{30}{60} \right) + \left( \frac{0}{3600} \right) = 1.5 \]

The Decimal Equivalent is 1.5 hours.
